HENRY H. LAMPER'I', OFCHICAGO ILLINOIS.

BAR SUPPORT AND SPACER.

Application filed April 6,

The main objects of this invention are to provide an improved form of bar support and spacer for use in the reinforcing systems of concrete construction work; to provide-a device of this kind having improved supportmg and spacing means which may be formed of wire and readily assembled; and to provide an improved bar support and spacer whereby the reinforcing bars may be supported in rows disposcd'in different planes.

An illustrative embodiment of this invention is shown in the accompanying drawing, wherein Figure 1 is a perspective of one of the improved devices.

Fig. 2 is a perspective of one of the devices used for supporting a row of reinforcing bars above another row.

Fig. 3 is a vertical section of a reinforcing system employing the devices shown in Figs. 1 and 2. p p In the form shown, the reinforcing system involves the use of a plurality of reinforcing bars 1, disposed horizontally above a falsework and supported in rows in substantially parallel spaced relation by the improved bar supports and spacers.

The support and spacer is preferably made of wire of comparatively heavy gauge which possesses the necessary rigidity and which may be bent to the desired form.

In the construction illustrated, the device comprises a supporting rod '2 which is spot welded or otherwise rigidly secured to a plurality of leg elements 3.

The leg elements 3 are of substantially identical construction and each comprises an arched spacing portion 4 of substantially inverted U-shape having substantially. parallel arms 5 and 6 disposed transversely of the rod 2. The arched portions 1 are disposed in substantially a single plane and are spaced apart so that the arms 5 and 6 form with the intermediate portions of the rod 2, a plurality of U-shaped seats 7 between the arched portions.

The arm 5 is considerably longer than the arm 6 and its end is bent at substantially right angles to the plane of the portion l'to form a foot portion 8. In assembling the structure, the leg elements are arranged as shown in Figs. 1 and 2 so that adjacent foot portions 8 extend in respectively opposite directions.

In order to permit the devices to be supenable them to rest reinforcing bars.

1928." Serial No. 267,902

ported one above another for supporting the reinforcing bars in rows, the foot portions of the devices above the bottom row are provided with aditional supporting means to upon the next succeding lower bars.

As shown in Figs. 2 and 3, the additional supportmg means comprises a pair of rods 9 secured to the foot portions 8 and disposed substantially parallel to the rod 2. V

In operation, the lower devices are placed on the falsework, not shown, and the first row of bars 1 is placed in the seats 7, Other devices are then placed above the bars 1 with the rods 9 resting directly on the lower bars. With this improved construction and arrangement of parts, a reinforcing system may be constructed involving any number of rows of bars.

Although but one specific embodiment of this invention has been herein shown and described, it will be understood that certain details of the construction shown may be altered or omitted without departing from the spirit 'of this invention as defined by the following claims.

I elaimz' 1. A device of the class described comprising a rod adapted to support a plurality of reinforcing bars, and a plurality of leg elements secured to said rod, each of said leg elements comprising an arched spacing per tionand a foot portion, the arched portions of said elements being'disposed in substantially the same plane and being spaced apart from one another to define seats for the reinforcing bars.

2. A device of the class described comprising a rod adapted to support a plurality'of reinforcing bars, and a plurality of leg elements secured to said rod, each of said leg elements comprising an arched spacing portion and a foot portion located on respectively opposite sides of said red, the arched portions of said elements being disposed in substantially the same plane and being spaced ap art from one another to 3., A device of the class described comprising a rod adapted to support a plurality of reinforcing bars, and a plurality of leg elements secured to said rod, each of said leg elements comprising an arched spacing portion of inverted U-shape and a foot portion, the

arched portions of said elements being disdefine seats for the posed in substantially the same plane and being spfllz'fidapa'ft from one another t0 define seats fd'r'flre reil'rfo'telrlg bars.

4. A device of the class described comprising a rod adaptedto support aplurality of reinforcing bars, and a plnralitycf'legelements secured to said rod, each ofsaid leg elements comprising an arched spacing portion and :1 foot portion, the arched portions of said elemenrs being disposed in substantially the same plane and being spaced apartfrom one amthen t0 definel'sente for the replnne.
